Abstract (en)

[origin: EP0186048A2] 1. Two-stage process for the preparation of glycidyl ethers of monovalent and/or polyvalent phenols, in which in the first stage, these phenols are reacted with epichlorohydrin at an elevated temperature in the presence of a basic catalyst, characterised in that the catalysts are dissolved in a portion of the epichlorohydrin and heated to a temperature of 90 to 130 degrees C and a solution of the phenols heated to 20 to 80 degrees C the remainder of the required quantity of epichlorohydrin is gradually added to the first mentioned solution and the reaction mixture is kept at the boiling temperature for 5 to 10 hours after all the solution has been added.
